Research On The Application Technology Of GIS Integration Development

Because the GIS software is a powerful tool for analyzing visible geospatial data, the GIS integration development based on GIS components and visible developing tools becomes the main trend of information system development. This dissertation describes some problems which come from the real project and give the solution of them. By using these solutions, those projects all have a wonderful effect.The creating and loading map features is the foundation of visible information in GIS integration system. The dissertation first analyzes the aspects of this matter and then gives an appropriate way of loading mass map features. The region statistic is another important function of GIS integration system. The dissertation gives a new algorithm based on map projection to solve this kind of statistic, and last it introduced the creating of theme maps.The position system realization is another problem which is always faced in GIS integration development. According to the position system of GPS, Address and Mobile Phone, this dissertation discusses the implementation of these system in real project.The contour map is widely used in GIS integration system. This dissertation first discuss the algorithm of creating rectangle regular net based on regular data and the algorithm of creating TIN based on discrete data, then analyze the algorithm of generate contour map based on these nets. At last the dissertation introduces the implementation of the algorithm which generate contour map based on regular data in real project, it also have a good effect.
